Title: Drug capsule for enteropathy and its production
Inventor: YAMASHITA TEIJI
IPC: A61K31/65
Filed: 1990-02-03
Abstract: PURPOSE:To obtain the subject capsule, capable of passing a drug for enteropathy through the stomach without bringing the aforementioned drug into contact with the gastric juice and releasing the drug at a desired enteral position by containing the above-mentioned drug for the enteropathy in a hardly digestible edible capsule and coating the resultant capsule with an edible substance without dissolving at an intragastric temperature. CONSTITUTION:A capsule is formed by using a solution of a film-forming hardly digestible edible polymer compound and plural holes (0.1-5mu, preferably 0.5-3mu size) capable of passing a drug therethrough are provided in the aforementioned capsule simultaneously or after the formation of the capsule. A drug for enteropathy is then contained in the above-mentioned capsule, which is subsequently coated with a material (e.g. edible hardened fats and oils) having >=35 deg.C, especially 45-60 deg.C melting point and hardly decomposed with the gastric juice. The part for releasing the drug can be controlled with the size and density of the holes provided in the capsule. Compositions of natural polysaccharides and polyhydric alcohol prepared by carrying out homogeneous kneading while heating the natural polysaccharides in a concentrated solution of the polyhydric alcohol, sugar alcohol, etc., are preferred as the hardly digestible edible polymer compound.

Title: Air volume adjusting-device
Inventor: NAKAJIMA YOICHI
IPC: F24F13/14
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To provide an air volume-adjusting device in which resistances against airflow under a full-opened state can be reduced and either noise or vibration as well as its loss can be restricted. SOLUTION: A vane base 12 for supporting a rotary vane 13 is arranged at an airflow-feeding pipe 11 in such a way that the vane can be turned by a predetermined angle. The rotary vane 13 is turned to adjust an opening area within the airflow-feeding pipe where the airflow can pass so as to adjust an air volume and further under a full-opened state, the vane base 12 and the rotary vane 13 are set to be in parallel with an axial direction of the airflow- feeding pipe. With such an arrangement as above, it becomes possible to keep a more opening area within the airflow feeding pipe 11 under the full-opened state, thereby reducing resistances against the airflow, a stable state can be assured against an air pressure to cause a pressure loss to be hardly generated and noise can also be reduced.  In addition, the airflow is not biased within the airflow-feeding pipe, a biased airflow or the like is not generated and no bad influence is applied to its downstream side.

Title: Ultrasonic wave diagnostic device
Inventor: SHINOMURA RYUICHI
IPC: G01N29/26
Filed: 1989-02-03
Abstract: PURPOSE:To enable the compatible connection of a plural-section image pick-up probe, a minor axis variable aperture prove, a minor axis focus probe and a two-dimensional array probe by making a plurality of connectors correspond to one probe arranged in plural lines. CONSTITUTION:As a probe 10, vibrator groups of plural lines are used as shown by 10a, 10b, with the vibrator group of each line being connected to an image pick-up device 2 by different connectors 3a, 3b, respectively, and in each vibrator line, beams are scanned in the major axial direction. At a result, the image of a fault plane 11B slightly shifted in the minor axial direction from a fault plane 11A can be picked up, and when two images are displayed, only one fault image is displayed at real time, and the other is made into the freeze state. In a device capable of switchingly displaying two probes at real time, fault planes 10A, 10B are displayed at real time, which is useful for image construction in the depth direction. The faults 10A and 10B may be successively displayed by one image display. Thus, when two-dimensional arranged probes, particularly, minor axis variable aperture and variable focus, are conducted, they can be realized at low cost and with satisfactory compatibility.
